To @ZZ whom it may concern.-

Be it known that I, JOHN ELLWooD LEE, a citizen of the United States,residing in Conshohocken, Pennsylvania, have invented certainImprovements in Machines for Winding Fabrics and other Materials intoRolls, of which the following is a specification.

My invention consists of an improved machine for winding fabrics andother materials into rolls of measured'lengths, and is more especiallydesigned for the winding up of gauze or similar material into rolls ofvarying sizes for surgical use.

VIn the accompanying drawings, Figure l is a Vertical section of awinding machine in conjunction with a side elevation ot' a feed .tablefor the winding machine. Fig. 2 is a plan view; and Fig. 3 is a frontelevation partly in section with the feed table removed.

Although I have shown the feed table X in conjunction with my windingmachine it will be understood that this feed table is not an essentialfeature, as the gauze or other fabric to be Wound up into measuredlengths may be fed directly into the machine from the roll, instead ofpassing over the feed table.

The frame of the winding machine consists of a box part A mounted uponsuitable -legs A the box part being left more or less open at the sidewhere the fabric enters the box. The fabric upon entering the box passesaround a suitable number of tension rollers a and around a measuringroller E to anotherv tension roller a2, and thence it is wound up on thewinding spindle F which is preferably made of square or other polygonalsection and tapering, (Figs. l and 2). This winding spindle F isprovided at its inner end with a handle F and has its squared partadapted to a corresponding opening in the hub of a Wheel f', while atits outer or smaller end it is adapted to a corresponding opening in thehub of a wheel f. These two driving wheels f and f are geared together,as through the medium of wheels f2, f3 at the opposite ends of asuitable shaft f4. Motion is imparted to either of these wheels f, fthrough any suitable means and thus the necessary motion for turning thespindle Ffor winding up the fabric is applied to both ends of thespindle. In the present instance I have shown this driving means asconsisting of a wheel f 5 suitably secured to the Wheel f and driven bya belt d3 from a wheel d on a driving or counter shaft d, Figs. l and 3.This wheel d is loose on the shaft d but can be thrown into geartherewith by means ofa suitable clutch cl2. Whenever this wheel d isclutched up to the shaft, the winding spindle will he rotated in thedirection of the arrow, Fig. l, and ifthe end of the fabric has beenpartially turned around the spindle F by the hand of the operator, thefabric will be wound up into a roll upon this spindle, until the machineis stopped or the supply of fabric gives out.

In order to secure the winding up of the fabric into rolls of measuredlengths, I combine with the drum E an automatic measur- -ing device, andin combination with that an automatic stop motion to cause the stoppageof the machine when any determined length of fabric has been wound upinto a roll.. In this case I have shown a horizontal measuringindicating disk B, which is geared up to the measuring roll E throughthe medium of any suitable systemof gear wheels.. By way of example, Ihave shown the connection as through gear wheels e, e', e2, this lastmeshing with a gear b on the under side of the disk B. The diameter ofthe measuring drum E may be any convenient unit of measurement, as forinstance the foot and the drum will be so geared up to the indicatingdiskB as to give the proper relation to the divisions for the disk. Forthe sake of example each division for the measuring disk may represent ayard, so that the disk B will be revolved with the measuring drum to theextent of one division of the disk for every three revolutions of themeasuring drum. I make use of this disk B as the means for automaticallystopping the winding when the desired length of fabric has been woundup. For this purpose I provide the disk with a series of radially adjustable stopping pins b to co-operate with the lhereinbefore mentionedclutch or other stop motion through suitable intermediate connections tostop the machine whenever that stopping pin b which has been moved outon the 'disk B shall have reached a given point in the rotation of thedisk. In this instance I have shown the clutch d2 as controlled by aweighted lever C through the medium of a connecting rod c', lever c2,pivotedatcto the IOO machine.

frame, connecting rod c3 and bell crank lever c4. This weighted lever Cis pivoted at 0 to the frame and is so arranged as to tend to throw theclutch d2 out of engagementwith the Wheel d and stop the winding. Thislever C may be provided with a handle c5 by which the operator maycontrol the clutch by hand. 'Through a slot in theback end of this leverC passes the lower end of a vertically movable latch rod G which isguided at its upper end in a slot in a bracket a of the frame of the Thelower end of this rod Gis pro vided with adjustable stop nuts g g aboveand below where it passes through the lever C to leave such play or lostmotion at this point of connection as may be found desirable. This rod Gis provided with a latch g2, which may conveniently be a separate piecefrom the rod but pivoted thereto. This latch is adapted to engage withthe under side of the bracket a but has its upper end passing up througha slot in the bracket and (when engaged with the latter) projecting intothe path of such of the stopping pins upon the measuring disk B as mayhave been moved out radially. y

As shown in the drawings, the latch g2 is engaged with the bracket,holding the rod G in its downward position and the Weighted end of thelever C elevated and the clutch cl2 clutching the wheel d to the shaftd, so that the windingisthen proceeding. As the winding proceeds and themeasuring disk B revolves in the direction of its arrow, Fig. 2, thatstop pin h which has been projected radially from the disk B will, whena certain number of yards have been wound up, come into contact with thelatch g2 and push it ont cf engage-y ment with the xed bracket a. Theweighted end of the lever C will then immediately fall and throw theclutch d2 to disengage the wheel d from the shaft d and stop thewinding. The operator at the same time cuts the fabric from the piece,removes the roll thus wound up, as hereinafter described, and starts therolling up of another length by raising the Llever C to throw the clutch(Z2 over and applying the end of the fabric to the spindle F. A springg8 on the bracket a acting on the latch g2 throws the latter intoengagement with the under side of the bracket a', to hold the lever C inposition, when raised, until a stopping pin b comes around to throw itout at the desired point@ In order that the operator may convenientlystop the winding independently of the automatic stop motion, there maybeprovided aleverH pivoted to a bracket a3 on the frame and having at itsupper end a pin h to act upon the inner side of the latch g2, While thelower end of the lever H hasa connecting rod h extending through to theoperators side of the machine, where it is provided with a suitablehandle. By pulling on this handle at any time, the operator candisengag'e the latch rod G from the bracket and stop the winding asalready described.v

In order that the fabric may be Wound up into rolls with true ends andwith dierent widths of fabric, I provide in the box A an adjustablepartition P, between which and the front wall a2 of the box A the fabricmay be guided in being wound up into the roll. This partition isprovided with openings for the free passage of the tension rods orrollers and the measuring roll E and is provided with a revolvingbushing p with a squared opening for the reception of the squaredspindle F. As shown in Figs. l and 3, this partition is guided upontransverse V-guides a4 in the botto-m of the'box A and has verticalbolts P adapted to turn in bearings with lower l threaded ends passingthrough slots in the bottom of the box A. On the under side of thebottom of the box are guide ribs a5 for the reception and guidanceofnutspupon the threaded ends of the bolts P. Owing to these guide ribsthe nuts cannot turn, so that by turning the bolts Pf as by handles p2at their upper ends, the partition may be clamped to the bottom of thebox A in any position to which it may be adjusted. In connection withthe winding spindle, removable blocks of various sizes may be providedto be placed in the bottom of the box A, as indicated at R in Fig. l, toact as surfaces against which each roll as it is about being completedmay bear, to make the final winding tight and compact.

To facilitate the removal of the wound-up roll from the machine, I makethe winding spindle F removable, as already explained, and combinetherewith whatIterm a knockout device. This may assume various forms butthat illustrated in the drawings and which I will now describe I havefound to answer satisfactorily.

K is the knock-out lever which in this instance is pivoted at k to abracket on the frame and has at its outer end a hammer head 7s. Thislever is under the control of the operator. In this case I have shown itas adapted to be operated by the foot acting upon a treadle lever Tpivoted at t0 to the frame and counter-Weighted at t. This treadle isconnected to the knock-out lever thro-ugh a link t2 and toggle leverst3, t4, connected at one end to the frame and at the other to the lowerend of the knock-out lever K. Instead of arranging this lever to strikethe end of the spindle F itself, I provide an intermediate plunger k2passing through the hub of wheel fand resting against the outer end ofthe spindle F. When the winding of a roll is complete, the operator byputting his foot upon the treadle T throws the knock-out lever K tostrike the plunger 7a2 and through it knock the spindle free from theroll and its bearings in the box, so that the operator can then easilywithdraw the spindle and remove the roll from the box. The spindle canthen readily be replaced for a new winding operation.

I claim as my inventionl. A machine for rolling band-age or other IIOmaterial, having a Winding spindle, driving Wheels through Which saidspindle passes and into Which it is detachably fitted andmeans forknocking the spindle free ot' said Wheels and of the wound-np roll offabric in the machine, substantially as described.

Y 2.
